Arlington and State of Virginia, has in,

vented certain new and useful Improvements in Metal Frames, of whichthe, following is a specification.

My invention relates to new and useful 1o improvements in metal frameswhich are` to be used on matches or the surrounding walls of other formsof opening; the frame being designed to protect the edges of the wallsof the opening and to also support a door or cover.

The present invention is a division of an application filed by ine onhatch covers and means for supporting and locking the saine, filedOctober 3, 1922, bearing Serial No. 2o 592,060. f

One of the objects of the present invention is to provide a frame whichis relatively light in weight, readily assembled, rigiid in constructionand relatively cheap to manufacture. 4

Still another object of the inventionfis to provide a frame, the partsof which may be interlocked and then riveted to form a substantiallyunitary structure. Also the ends of certain o-f the parts of the framewill be slightly offset so that when the framey is assembleclfthe loweror bearing surface of the fra-me will be flush throughout.

Still another object of the invention is to provide a frame that mayV beattached, if desired, to afrefrigerator type car roof about a hatch, theframe thus protecting the side walls ofthe hatch where they projectabove the level of the car roof and also protect the upper edge or uppersurface of these walls. As is well known, the hatch of a refrigeratorcar has its walls extending slightly abovethe 'level of the car roofandv ony the insertion of the ice in the hatch, these walls becomedamaged and splinter, so that the cover of the hatch, when closed, willnot form a tight connection therewith.

Referring now to the drawings showing a preferred embodiment of iny'invention,

Fig. 1 is a top plan view of the hatch frame in its assembled position;

Fig. 2 is an enlarged detail of one of the corners of the frame;

Fig. 3 is a side elevation of the corner of the` frame, the latter beingtilted for the sake of clealness of illustration.

Fig. 4 is a fragmentary section taken on line 4-4 of Fig. 2 looking inthe direction of the arrows; and

Fig. 5 is an enlarged detail of a corner similar to Fig, 2 but beforethe two parts are in their final set position.

Referring now more in detail to the several figures, there yis shown theframe which consists of the rear piece 1, and the;

front piece 2, 'in which are fitted the side pieces 3 and 4, as will beshortly described.

These front and rear pieces each consistsvof what *I terni the base o1'body 5, and may be of vany desired weight and thickness, and may beformed of iron, cast steel or inalieable iron. The rear piece 1 hasformed thereon the brackets 6 for the reception of the hinge pintles,while the front piece 2 has a bracket 7 for the. reception of a hasp orlink, as may be desired. The outer edges of these 'bases may be roundedat intervals as at 8 to provide a. sufiicient thickness of metalopposite the bolt or lag screw holes 9, In a like manner, theA sidepieces 8 and 4 have their bases rounded at points along the edges for asimilar purpose. j

Referring now to the front piece 2 of the frame, it will be seen thatextending nearly its entire length is the upstanding wall l() which iscurved at rightangles at its opposite ends as at 11, and extending fromthe top of this wall inwardly (with relation to Fig. l), there isprovided the flange v12, while from the router edge a short downwardlyextending wall 13 may be provided as shown in dotted lines in Figs. 2, 3and 5.

As may be seen in Fig. 4, the base of this front piece is slightlyoffset at its ends,'as at 14, so that when the sides 3 and 4 arepositioned, as will be .shortly mentioned, the side together ywith thefront and rear pieces will present a plane surface throughout theirlength. The rear piece 1 is also formed with the wallsy and flangessimilar to the front piece just described, as may be clearly seeny thefull length of the flange 12, but stops short of its ends as shown bythe dotted lines 15.

they are likewise provided with an upstandying wall 16 and the inwardlyextending flange 17 and the small downwardly. extendingV wall 18, whileat the opposite ends of these pieces and extending beyond the ends ofthe-wallsv 16 .are the raisedtongues 19 `to itwithin the socketsformed'by the bending of the walls 10 and flanges 12, at their cornersas shown at '11 heretofore mentioned. The ends'of these side pieces fitagainst the offset-portions of the frontand rear pieces,as-alsopreviously mentioned, and then are riveted as shown at 20. TheWalls 10 and flanges V12 registerjwi-th the walls." 16 and anges 17 whenallthe parts'are in position as will be' readily understood from theseveral ligures.

From the foregoing it; will beseen that I have provided a frame wherein'the four parts substantially interlockV after which they will besecurely riveted to each other,

Y thereby- Vforming an exceedingly strong and Y rigid structure.

It will also be seen that if thesframe is placed about the walls of ahatch, it will protect itfroni any damage from its sides while theoverhanging flanges will securely protect the upper edges of the wall-s.Furthermore, it will be seenv that the frame is one that. may bey'manufactured and then shipped in a knocked-down condition, and thenmay be quickly assembled and riveted at its` four corners, when desired.

' Many slight changes Vmay be made Without departing from" the spiritand-scope of my invention.V Y Y I vHaving thus described my invention,what 1 claim asnew and desire to secure by Letters Patent is 1. A metalframe ,comprising front,vrear and yside pieces, .all ofv which are:provided with upstanding walls which register when theY frame visassembled, lsaid walls-having registering fianges extending inwardly toform a-rim, the several walls interlocking inV la telescopic manner whenthe frame 1s assembled andthe said pieces alsorigidly secured to eachother at their ends. A

2.- AV metal frame comprising front,'rear `and side pieces all of whichYarepprovided Y with upstanding walls which register vwhen the frame isassembled,sai d walls Yhaving flanges yextending inwardly andYregistering therefrom to form a rim, ythe-wallsV on the front and Arearpieces *curvedV at their opposite ends and these curved portionstogether with the end portions of the flanges of these pieces formingreceptive chambers, the

`side pieces `provided with raised portions at their ends to engageV thewalls of sald receptive chambers to thereby interlock `the several partsand the several parts'also riveted to each other at their several ends.y

3. A frame comprising a front and rear piece, each of said piecesprovided with an upstanding wall extending substantially throughout itslength, said wall curved at its opposite ends, said wall also provided`with an inwardly extending YVflange, side pieces, each of which is alsoprovided with an upstanding wall and adapted to register with the wallsof the front and rear pieces when'the frame is assembled, each of thesaid Walls of said side pieces provided with an inwardly extendingliange and said side pieces provided with-a tonguelocated be,- yond theends of said walls to fit within the curved wallof the front and, rearpieces, and the several parts riveted together at the four corners ofthe-frame. Y n

' 1. A frame comprising front, rear and side pieces, the ends of theselfront andrear pieces oiset on their under surface at their oppositeend, and the ends of the sidepiec'es secured yto the yodset ends tothereby present a flush under surface for the entire frame, each of theseveral parts of the king a base and an upstanding wall atV its inneredge and a rim-extending fromsaid wall, all of said walls rand rimsregistering when the frame is` assembled, raised portions formed ontheends of twoof the piecesof the Vframe to interlock with the other twopieces when thezframe is assembled, andthe ends of the front and rearportions offset so as :to :present a plane under surface to kthe entireframe when the same is assembled and theseveral pieces riveted to eachother-at their ends. V Y Y VIn testimony whereof I aflix my si nature.
